Specialized Fireproofing for St. Louis Commercial Projects
Structural steel loses its strength during a fire, which puts the entire building at risk.
Niehaus Building Services delivers the exact, code-compliant fireproofing you need to protect your structure and keep occupants safe.
Our team handles material ratings, proper jobsite sequencing, and trade coordination so you avoid failed inspections, ruined equipment, and scheduling bottlenecks.
Why Choose Niehaus Building Services for Your Fireproofing Project?
Decades of Technical Expertise
Fireproofing is a compliance-heavy trade. We understand complex UL-Listed designs and exact building code mandates to ensure your structure passes inspections.
Single-Source Project Efficiency
Because we self-perform drywall, framing, and specialty finishes, you get seamless trade coordination and a single point of accountability.
Zero Guesswork on Sequencing
We know exactly when to spray. Our team coordinates closely with mechanical, electrical, and plumbing trades to protect your schedule and their installations.
Vetted Safety & Low EMR
With an impressive .80 EMR safety rating, our union crews adhere to strict jobsite safety protocols on complex commercial builds.
Manufacturer-Backed Warranties
As licensed installers for W.R. Grace, Cafco, and Carboline, our work fully meets manufacturer standards to safeguard your project warranty.
Proven Multi-Story Capability
From small commercial maintenance packages up to $20,000,000 multi-story high-rises, we have the specialized equipment and manpower required to scale.
High-Performance Fireproofing Systems We Install
We apply a full range of fireproofing materials to protect your structural steel and meet building codes, whether the elements are hidden behind drywall or left completely visible.
Cementitious Spray-Applied Fireproofing (SFRM)
We use professional-grade pumping and spraying equipment to apply durable wet- or dry-mix formulations. This is a highly efficient, budget-friendly way to protect concealed structural steel, metal decks, beams, and columns.
Intumescent Fireproofing Coatings
Our team is manufacturer-licensed to apply these specialized, thin-film coatings that expand during a fire to protect the steel. We use precision mil-thickness gauges to ensure compliance with architectural exposed structural steel (AESS) where you want to maintain a clean, modern look.
Mineral Fiber Spray Application
We spray high-density fiber insulation directly onto metal decks and structural members. This requires specialized commercial rigs to achieve uniform coverage, providing both structural fire protection and thermal efficiency.
